Ma man rnnrrre SIGNAL.

Application filed April i To (all LU/HUM it may 0072067'7'1.

Be it known that we, JOHN C. llroninir and Srnvnwrna ELMLINGER, citizens of the United States, residing at Reading, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in a Traffic Signal; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a trailio signal for automobiles and other vehicles.

It is aimed to provide a signal which is operable to various positions according to traflic rules or regulations in simulation of the human hand; one which maybe made preferably of celluloid, suitably colored, and adapted to be illuminated during the hours of darkness, and which may be used on open and closed automobiles or vehicles; one which is readily attachable to all makes of automobiles, as to the windshield frame thereof, and one embodying a novel con struction consisting of the details, combinations and arrangements of the parts as hereinafter set forth with relation to accompanying drawings illustrating practical embodiments.

. In said drawings Figure 1 is an elevation showing our improved signal in connection with fragmentary parts ofan automobile and as viewed from the drivers seat;

Figure 2 is a plan view of the signal apparatus alone;

Figure 3 is a horizontal longitudinal sectional view on the line 33 of Figure 1;

Figure 4 is a vertical sectional view on the line 4lof Figure 1;

Figure 5 is a side elevation of a modified form of traffic signal, and

Figure 6 is a detail perspective view of a member of the attaching clamp used in connection with the form of Figure 5.

like reference characters designate like or similar parts in the different views.

Referring first to the form of Figures 1 ,to 6 inclusive, a signal arm is provided which is generally designated This arm may consist of a tube 10 adapted to be pivoted for swinging movement in a vertical plane from a vertical position in which it normally hangs. The tube 10 is adapted to be screw threaded as at 11 into a block or head 12, preferably of msulatlon as shown. liiemow 1922. Serial NO. 549,399.

ably fitting the block 12 and surrounded by the tu e 10 is a terminal plug 13, preferably of insulating material, to which conductor wires 14:, passing through the tube 10 are fastened. Tires 14. may enter the tube 10 through a suitable opening as at 15. An electric bulb 16, preferably of the usual type, is screw threaded or otherwise removably fastened as at 17 in the bore of the block or head 12 into conducting relation with the wires 14- or their terminals at the plug 13. The block 12 is exteri'orly sore-w threaded and adapted to'have a signal member 18, which is interiorly. screw threaded as at 19,

.detachably engage the same. The signal element 18 is hollow and of any suitable.

material, preferably transparent ortranslucent. We find that celluloid forms a good material and the back thereof is preferably colored red and the front side is colored white or cream. A bell-shaped reflector 20 may be associated with the bulb 16, having an opening through which. the bulb is passed'in attaching it and by means of which the reflector is removably secured in place. i

The signal arm A may be suitable manner. The means shown particularly adapts it for mounting on a sedan, coupe or other closed automobileor vehicle as suggested at B. To this end a hearing or bracket as at 21 is secured to the frame of the wind shield or other part ofthe vehicle as at C by means of screws 22 passing through suitable openings in the bearing or bracket. Said bracket 21 is preferably curved or shaped to adapt itself-to the surface of the part C to which it is fastened. Passing through an opening 23 in the bracket 21 is a sleeve 24 secured in place by means of nuts 25 screw threaded thereon and adapted to engage one on each of opposite sides of the bracket. A pivot rod 26 is journaled in the sleeve 24; for movement on a horizontal axis and the rod 26 passes through an opening 27 in the rod 10. Rod 27 also has an offset or crank extremity at 28 which passes through an opening 29 in the rod .10 and thus connects the rod 24: with the arm A. for unitary movement. Suitably secured to the free end of the rod 26 is an operating crank arm 30 which may be provided with a knob 31. y

The electric current for the lamp 16 preferably utilizes the storage battery with which the automobile B is equipped and mounted in any pivot at 35.

the wires 14 may lead from the lighting switch of the automobile which is suggested at D and disposed for instance on the dash board at E. The switch D serves as a master switch for all lights of the vehicle and the lamp 16. The lamp 16 also preferably has an independent switch as at 32, disposed at any suitable location in connection with the wires 14 and preferably arranged upon the dash or in any convenient position I As a result of the construction described. the bulb 16 may be illuminated or extinguished as desired through manipulation of the switches D and 32. When a signal is to be given, the crank 36 is turned the proper degree according to trallic regulations or rules, so as to switch the arm A and particularly the signal element 18 in a vertical plane from the rod 26 as an axis. The arm A normally hangs vertical as will be understood.

In order that the operating parts may he detachable, the nut 32 is screw threaded as at 33 to the rod 26.

Referring now to the modified form shown in Figure 5, a signal arm here designated is'similar to the signal arm A in construction and operation, aside from the construction of the tube 10, the equivalent of 'which is here designated as 34:. The differencein the'tube 34: over the tube 10 resides in its pivotal connection at '35 for movement on a horizontal axis so that the signal arm F may be swung in vertical plane and in the provision of a handle at 36, of wood 'or othersuitable material. A two part clamp is used to secure this form in place and as the parts are designated 37, being suitably shaped to embrace the frame G of a wind shield or another suitable part. The sections or parts 37 are secured removably and adjustably together by means'of a bolt at 38 and a stud or post extends rigidly from one of the sections to form the said In this instance. the switch 39, which is the'equivalent' of'the switch 32 is located at any suitable point, as on the vehicle. This particular form is well adapted for use on open cars in view of the ready detachability of the simple clamp to the windshield frame.

As merely practical embodiments have been shown by way of example, it is to be understood that changes in the details may be resorted to provided they fall within the spirit and scope of the invention.

What is claimed is 1. A traiiic signal having a rod, a head screw threaded on said rod, a lamp carried by said head, conductor means passing through said rod to said lamp, said head be ing exteriorly screw threaded. and a hollow signal element screw threaded to said screw threads, and disposed over said lamp.

2. A traffic signal having a hollow signal element, a head in screw threaded engage ment with said element a lamp detachable on said head, a reflector positioned by said lamp a plug carried by said head in conducting relation with the lamp a tube screv threaded into said head and conductors passing throughsaid tube to said plug.

. 3. A traflic'signal having a signal arm. means to mount said arm consisting of a rod. said rod having a main portion and a terminal portion spaced therefrom, the rod at said portions extending through the arms, and means to pivotally mount said rod and prevent displacement of said portions from said arms. i
